Slip brass nipple and associated method

Abstract

A slip brass nipple includes a tubular brass body that may be approximately 6 inches long. The apparatus includes a threaded proximal end, a non-slip gripping portion and an open distal end n. The open distal end includes an internal stop to allow a copper pipe to slip in and terminate at a predetermined distance such that the gripping portion may be used to tighten onto a female tube fitting. The apparatus advantageously enable galvanized and copper pipes to be connected together while significantly reducing the risk of galvanic corrosion caused by a dielectric reaction between the galvanized steel and copper pipes. The slip brass nipple may be manufactured in ½, ¾, 1, 1¼, 1½ and 2 inch diameters and may be manufactured according to brass material regulations in the industry.

What is claimed is: 
     
       1. A slip brass nipple for preventing galvanic corrosion caused by a dielectric reaction, said slip brass nipple comprising:
 a brass body including
 an open, threaded proximal end; 
 a gripping portion integrally formed with an outer surface of said body; and 
 an open distal end spaced from said gripping portion; 
 
 wherein said open distal end includes an internal stop formed at in interior surface thereof; 
 wherein said body has first and second diameters, said first diameter beginning from said open distal end and terminating at said internal stop, said second diameter beginning from said open, threaded proximal end and terminating at said internal stop; 
 wherein said gripping portion has an outermost surface provided with a plurality of indentations for creating a non-slip region; 
 wherein said second diameter extends along a major longitudinal length of said body; 
 wherein said first diameter extends along a minor longitudinal length of said body; 
 wherein said outer surface of said body has a uniform outer diameter continuously extending entirely along said minor longitudinal length of said body and a portion of said major longitudinal length of said body. 
 
     
     
       2. The slip brass nipple of  claim 1 , wherein said body is entirely hollow and is provided with non-uniform passageway formed therein, said passageway extending through an entire longitudinal length of said body. 
     
     
       3. The slip brass nipple of  claim 1 , wherein an outermost diameter of said open, threaded region is smaller than an outermost diameter of said gripping portion. 
     
     
       4. The slip brass nipple of  claim 1 , wherein said first and second diameters uniformly extend along minor and major longitudinal lengths of said body, respectively. 
     
     
       5. A slip brass nipple for preventing galvanic corrosion caused by a dielectric reaction, said slip brass nipple comprising:
 a tubular brass body including
 an open, threaded proximal end; 
 a gripping portion integrally formed with an outer surface of said body and located adjacent to said proximal end; and 
 an open distal end spaced from said gripping portion; 
 
 wherein said open distal end includes an internal stop formed at in interior surface thereof; 
 wherein said body has first and second diameters, said first diameter beginning from said open distal end and terminating at said internal stop, said second diameter beginning from said open, threaded proximal end and terminating at said internal stop; 
 wherein said gripping portion has an outermost surface provided with a plurality of indentations for creating a non-slip region; 
 wherein said second diameter extends along a major longitudinal length of said body; 
 wherein said first diameter extends along a minor longitudinal length of said body; 
 wherein said outer surface of said body has a uniform outer diameter continuously extending entirely along said minor longitudinal length of said body and a portion of said major longitudinal length of said body. 
 
     
     
       6. The slip brass nipple of  claim 5 , wherein said body is entirely hollow and is provided with non-uniform passageway formed therein, said passageway extending through an entire longitudinal length of said body. 
     
     
       7. The slip brass nipple of  claim 5 , wherein an outermost diameter of said open, threaded region is smaller than an outermost diameter of said gripping portion. 
     
     
       8. The slip brass nipple of  claim 5 , wherein said first and second diameters uniformly extend along minor and major longitudinal lengths of said body, respectively.
